On-Board Diagnostic system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) • in the instrument cluster
~ page 14, fig. 7 is part of the On-Board Diagnostic (OBD II) system.
Th e warn ing/indicator light illuminates when the ignition is switched
on and goes out after the engine starts and the idle has stabilized.
Thi s ind icates that the MIL is working properly.
If
the light does not go out after the engine is started, or illuminates
while you are driving , a ma lf u nction may exist in the engine system.
If the light illuminates, the catalytic converter could be damaged.
Continue driving
with reduced power (avoiding sustained high
speeds and/or rapid accelerat ions) and have the condition corrected .
Contact your authorized Audi dealer .
If the light i lluminates, the electronic speed limiter may also be
malfunctioning. For more information~
page 26, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to
illuminate (only vehicles with gasoline engine)~

On-Board Diagnostics
Fig . 15 Location of
Data Link Connector
( DLC)
On-Board Diagnostics monitors the components of your emission
control system. Each monito red component in you r engine system
has been ass igned a code. I n case of a malfunct ion, the component
wi ll be ident ified and the fau lt stored as a code in the control module
memory .
The MIL light may also illuminate if there is a leak in the on-board fuel
vapor recove ry system. If the light illuminates after a refuelling, stop
the vehicle and make sure the fuel filler cap is properly closed (only
veh icles with gasoline engine)~
page 290.
I n order to make an accurate diagnosis, the stored data can only be
displayed using special diagnostic equipment (generic scan tool for
OBD).
In order to connect the special diagnostic equipment, push the plug
into the Data Link Connector (DLC). The DLC is lo cated to the right of
the hood release ~ fig. 15.
Your authorized Audi dealer or qualified workshop can interpret the
code and perform the necessary repair .•
Electronic speed limiter
Your vehicle may be factory equ ipped w ith tires that are rated for a
maximum speed of 130 mph (210 km/h). This is less than the
maximum speed of your veh icle. T o reduce the risk of sudden tire
fai lure and loss of contro l if the vehicle is operated at excessive
speeds, your vehicle a lso has an electronic speed limite r. The elec­
tronic speed limiter prevents your vehicle from going faster than the
tire speed rating. For more information ~
page 326.
If the eng ine control unit receives faulty veh icle roadspeed signals,
the Malfunction Indicator Lamp (M IL) ..... will illuminate. If this
occurs, contact the nearest authorized Aud i dealer for ass istance . _.,

& WARNING
Always observe the post ed speed limits and adjust your speed to
s uit prevailing road , traffic and weather condition s. Never drive
your vehi cle faster than the m aximum sp eed rating of the tires
installed .•
